| (54) | Lens moving unit and camera module having the same |
| (57) A lens moving unit is disclosed, the unit including a first lens moving unit including
a bobbin mounted at an inner side with at least one lens and formed at a periphery
with a first coil, and a housing configured to support a magnet arranged at a surrounding
of the bobbin to move the bobbin and the first coil to a first direction parallel
with an optical axis in response to interaction between the magnet and the first coil,
and a second lens moving unit including a base spaced apart at a predetermined distance
from the bobbin and the first lens moving unit, a support member configured to movably
support the first lens moving unit to second and third directions relative to the
base and to supply an electric power to the first coil, and a circuit board including
a detection sensor configured to detect positions of the second and third directions
of the second lens moving unit relative to a second coil and the base opposite to
the magnet of the first lens moving unit to thereby move an entire first lens moving
unit including the bobbin to the mutually different second and third directions which
is perpendicular to the optical axis in response to the interaction between the magnet
and the second coil.
